Claim Rejections - 35 U.S.C. § 112 second paragraph
4. The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
4a. Claims 1-12, 14-16, 18-20, 22-25, 27, 30-45, and 48-49 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention.
Claim 1 is vague and indefinite for several reasons.
Claim 1 is vague and indefinite because the claim references specific point mutations that are designated at specific amino acid residues within a parent polypeptide. However, the claims do not provide a parent polypeptide (amino acid sequence of specific SEQ ID NO), and therefore, it is impossible to determine where these substitutions would occur. Without a parent polypeptide (SEQ ID NO), there is no way to identify the correct residue for the substitution, to determine whether the parent polypeptide has the required base amino acid, and to confirm that the mutated polypeptide has the appropriate substituted amino acid (See specification, page 25, Table 5). The scope of the recited polypeptides is also indefinite because there is no way to determine at which position any given amino acid will be located. It is suggested that the claim be amended to recite the specific SEQ ID NO for the Fc polypeptide, with the specific mutations at the specific amino acid locations in the SEQ ID NO for the Fc polypeptides.
Similarly, claims 4-12, 14-16, 18-20, 22, 25, 27, and 48 are vague and indefinite because the claims reference specific point mutations that are designated at specific amino acid residues within a parent polypeptide. However, the claims do not provide a parent polypeptide (amino acid sequence of specific SEQ ID NO), there is no way to identify the correct residue for the substitution.
Claim 1, lines 2-5, 8, 12, are vague and indefinite because it recites “CH3 domain” however, without a reference SEQ ID NO, it is unclear what position this CH3 domain sequence is in the first Fc polypeptide and in the second Fc polypeptide.
Similarly, claims 2-3, 9-12, 14-16, 18-20, 22-25, 27, 34-35, and 48 are vague and indefinite because they recite “CH3 domain” however, without a reference SEQ ID NO, it is unclear what position this CH3 domain sequence is in the first Fc polypeptide and in the second Fc polypeptide.
Claim 2, line 2, is vague and indefinite because it recites “60°C or higher” and there is no upper limit to the temperature limitation recited in the claim.
Similarly, claim 48, line 18, is vague and indefinite because it recites “60°C or higher” and there is no upper limit to the temperature limitation recited in the claim.
Claim 11, lines 5, 7, 9, is vague and indefinite because it recites the limitation “and/or” and it is clear whether the limitation following “and/or” is part of the claimed invention.
Similarly, claims 15, 19 is vague and indefinite because it recites the limitation “and/or” and it is clear whether the limitation following “and/or” is part of the claimed invention.
Claim 23, line 3, is vague and indefinite because it recites the limitation “introduce cysteine residues capable of forming a disulfide bond”, however, it is unclear from the claim where the specific cysteine residues are introduced within a parent polypeptide, since the claim does not provide a parent polypeptide (amino acid sequence of specific SEQ ID NO), and therefore, it is impossible to determine where these cysteine residues would be introduced in the parent polypeptide.
Similarly claims 24 and 25 are rejected as vague and indefinite because they recite “introduce cysteine residues”, however, it is unclear from the claim where the specific cysteine residues are introduced within a parent polypeptide, since the claim does not provide a parent polypeptide (amino acid sequence of specific SEQ ID NO).
Claim 34, is indefinite because it recites the limitation “α-tailpiece”, without a reference SEQ ID NO.
Claim 37, is indefinite because it recites the limitation “J chain”, without a reference SEQ ID NO.
Claims 30-33, 36, 38-45, and 49, are rejected as vague and indefinite insofar as they depend on the above rejected claims for their limitations.
Conclusion
No claim is allowed.
Claims 1-12, 14-16, 18-20, 22-25, 27, 30-45, and 48-49 are rejected.
